Blue Ghost Mission 1 was an automated Moon landing endeavor conducted by Firefly Aerospace, which launched on January 15, 2025, and achieved a gentle touchdown on the lunar surface at 08:34 UTC on March 2, 2025. This accomplishment marked Firefly as the first private enterprise to successfully execute a complete soft landing on the Moon. Operating under NASA's Commercial Lunar Payload Services initiative, the mission deployed ten scientific and technological payloads designed to facilitate forthcoming human missions within the scope of the Artemis program. Approximately five hours following lunar sunset on March 16, 2025, the lander's solar-powered batteries were exhausted, resulting in loss of communication. The mission formally concluded at 23:25 UTC.
The Blue Ghost lander lifted off from Kennedy Space Center aboard a SpaceX Falcon 9 Block 5 rocket, which also transported the Hakuto-R Mission 2 lander. It delivered ten payloads to Mare Crisium, a lunar basin. The mission spanned 60 days with objectives including regolith analysis, geophysical studies, and examination of solar wind interactions with Earth's magnetic field. The scientific instruments comprised a regolith adhesion experiment, a lunar retroreflector for high-precision ranging, a radiation-hardened computer, thermal sensors, among others.
All ten NASA-provided payloads—such as GNSS tracking equipment, heliospheric X-ray imagers, magnetotelluric sounders, and radiation-tolerant computing units—activated successfully, gathered data, and transmitted over 110 GB of information back to Earth.
Mission
On February 4, 2021, NASA awarded Firefly a contract valued at US$93.3 million to deliver ten scientific investigations and technology demonstrations to the lunar surface by 2023. This agreement was part of NASA’s Commercial Lunar Payload Services (CLPS) program aimed at partnering with commercial entities for expedited lunar payload delivery under the Artemis program framework.
On May 20, 2021, Firefly chose SpaceX’s Falcon 9 Block 5 rocket as the launch vehicle for Blue Ghost’s maiden flight due to its greater thrust and payload capacity compared to Firefly’s own Alpha rocket. Subsequent Blue Ghost missions are expected to utilize Firefly’s forthcoming Medium Launch Vehicle.
Key development milestones followed: on April 26, 2022, Firefly completed the Integration Readiness Review for the lunar lander with an initial launch planned for 2024. By November 2023, the launch timeframe was narrowed down to between Q3 and Q4 of that year. In May 2024, Nammo UK finalized production of the LEROS 4-ET engines for Blue Ghost, which were integrated by June. Preparations advanced as scheduled with a reaffirmed goal of launching in Q4 2024. Environmental testing commenced in August at NASA's Jet Propulsion Laboratory (JPL).
In November 2024, Firefly declared that Blue Ghost was fully ready for launch targeting mid-January 2025. Payload encapsulation was completed by January 10. On January 15, 2025, Blue Ghost lifted off from Kennedy Space Center Launch Complex 39A aboard a SpaceX Falcon 9 Block 5 rocket. The mission included the co-manifested payload from Hakuto-R Mission 2.
Following a 25-day Earth orbit phase, the spacecraft executed Trans-lunar Injection and Lunar Orbit Insertion maneuvers. After spending sixteen days in lunar orbit, it performed a powered descent and achieved a soft landing northwest of Mons Latreille at 2:34 a.m. CST on March 2, 2025. This success established Firefly as the first commercial entity to accomplish a fully successful soft Moon landing. The mission duration corresponded approximately to one lunar day (~14 Earth days), during which three solar panels powered scientific instruments and spacecraft systems until temperatures dropped sharply after lunar sunset.
Hardware
Blue Ghost featured composite decks, struts, landing legs, and footpads fabricated internally. Its thermal management system integrated heaters, temperature sensors, and Multi-layer insulation. Firefly was responsible for designing and producing the onboard avionics and battery systems, while solar panels capable of generating up to 400 watts of power were supplied by SolAero, a Rocket Lab subcontractor. Rocket Lab’s ASI division provided critical support including ground and flight software, trajectory planning, orbit determination, and software testbed integration. The propulsion system consisted of a Nammo LEROS-4 main engine, eight Firefly Spectre bipropellant thrusters, alongside four clusters of Firefly cold-gas Attitude control system thrusters. Communication capabilities employed both S band and X band radios, utilizing ground stations operated by the Swedish Space Corporation. Two Firefly gimbals allowed precise aiming for the X-band antenna, LuGRE antenna, LEXI telescope, and NGLR Retroreflector. Assembly and integration took place in Firefly’s cleanroom located in Cedar Park, Texas, followed by testing within the Jet Propulsion Laboratory’s Thermal vacuum chamber.
Firefly emphasizes its comprehensive in-house production and validation of Blue Ghost’s structural components as a significant competitive advantage among CLPS landers.
Payloads
The mission focused on Mare Crisium, a lunar basin observable from Earth. The lander’s scientific instruments gathered data regarding the properties of lunar soil, geophysical characteristics, and interactions between the solar wind and Earth's magnetic field, aiding preparations for future crewed lunar missions.
The payload suite, totaling approximately , included:
- Regolith Adherence Characterization (RAC), which evaluated how abrasive lunar dust adheres to materials such as solar cells, coatings, and sensors—derived from the ISS MISSE-FF experiment.
- Next Generation Lunar Retroreflectors (NGLR), designed to facilitate high-precision Earth-Moon laser ranging for investigations into lunar interior composition and fundamental physics.
- Lunar Environment Heliospheric X-ray Imager (LEXI), developed by Boston University College of Engineering to capture images of Earth's magnetosphere interacting with solar wind over a ten-day period encompassing a total solar eclipse.
- Reconfigurable, Radiation Tolerant Computer System (RadPC), demonstrating radiation-hardened computing technology essential for electronics functioning within the Moon’s intense radiation environment.
- Lunar Magnetotelluric Sounder (LMS), aimed at analyzing lunar mantle structure through measurements of electric and magnetic fields across 700 square meters.
- Lunar Instrumentation for Subsurface Thermal Exploration with Rapidity (LISTER), designed to drill between 7 and 10 feet into regolith to assess lunar heat flow.
- Lunar PlanetVac (LPV), intended to collect regolith samples either for onboard examination or eventual return to Earth.
- Stereo CAmeras for Lunar Plume Surface Studies (SCALPSS 1.1), tasked with capturing images of surface disturbances during landing to study rocket exhaust effects on regolith displacement.
- Electrodynamic Dust Shield (EDS), which produces electric fields to repel dust particles with potential applications on thermal radiators, spacesuits, visors, lenses, and solar panels.
- Lunar GNSS Receiver Experiment (LuGRE), successfully receiving GPS and Galileo signals at lunar distances to validate concepts for lunar navigation systems.
